Screwed up AC while doing RECALL Service

Screwed up AC while doing RECALL Service

I visited to complete my recall service last week 05/23/2015 at Lone Star Toyota of Lewisville Tx, during that service they screwed up car AC, its suddenly stop working. I took appointment on 05/30/2015 12:00 noon and after visiting the service station, the guy name JEREMY said we donot have any space its full for today so come next week, I said I have took the appointment so you should take my car , he said there is no appointment on your name and then I call the service station to confirm the appointment and they have my appointment in the system and then I asked to talk to their manager , he is also repeating the same story he said your appointment is there but we have lots of walking so we wont be able to take your car today

They just avoid to fix this as they screw up the ac and now they have to fix this at no cost.

My Question to TOYOTA if you are fixing the recall at no cost and putting other defects in the car who is responsible for that.

I am going to take this up higher, I am not going to live this.
